My invention relates generally to cartons, and more particularly to abox or carton which has a hinged side whereby entry or removal ofdelicate or fragile goods or merchandise, such as pastry, isfacilitated.

outwardly folding webs whereby'they serve as pockets to receiveretaining means which prevents accidental lowering of the hinged wall orside. v

Additionallyfithese pockets have tapered sides contacting the depending,top tabs whereby the top of the box is directed toward and held in itscorrect and exact position. More s ciflcally, the depending top flap isheld between he hinged wall and the doubled front edges of the sidewalls.

Yet another advantage resides in the cutting away of the webs so thatthe outer walls of the locking pockets are positioned below the innerwalls, the inner walls thus serving as guiding faces for thepockets.Also, the incline of the outer walls aidsin easy entry of the tabs onthe upper side walls.

Another feature is the rounding of the depending tabs so as to preventany curling thereof, this flatness permitting their easy and efilciententry into their pockets.

Another feature is my association ofa. locking means for the medial partof the hinged wall and the adjacent wall, this locking means comprisingonly slits in the hinged'wall, and these slits having their innerterminal portions at an angle to x the direction of outward removalmovement of the cake or the like whereby any distortion of thelocking.'m eans from the original plane of the front wall will not causeany snagging to occur between theplate or paper carrying the cake andthe front wall. It is to be noted that the locking means is initially,flat and remains so until after entryof the article into. the boxandupward and locking movement of the front wall.

4 The invention consists in the details of'construction and in thecombination and arrangement of the several parts of my improved paperbox whereby certain important advantages are attained and the device isrendered simple, inexpensive and convenient and advantageous for use,all as will be hereinafter more fully set forth.

In order that my invention may be the better understood, I willnowproceed to describe the same with reference to the accompanyingdrawings, wherein- Fig. 1 is a plan view of a blank from which a This,box may be constructed in accordance with and as an embodiment of myinvention.

refer to similar parts Asshown in Fig. 1, the complete box blank Thebottom so has side flaps l5, slit as mm cated at "5.. Theseside flapsfold upwardly at right angles to the bottom it) along the scored lines8. The back if has side flaps ll curvably extended at l8 and notched atis. As shown in Fig. 2, the flaps I! are folded forwardly about scoredlines 'I after the back if has been folded upwardly about the dottedline 20, this dotting indicating a'scoring, and the curved portions I1enter the slits IE to lock these several members in position.

The top I! has flaps 2| provided with tabs 22, and these flaps arefolded downwardly about the dotted or scored lines 23 after the completetop portion is folded about the line 28. These flaps 2| lie on the outersides of the flaps I5. See Fig. 2.

The flap l3 has a. locking element 21. Both the locking element 2! andthe flap l3 fold downwardly about the dotted line 28, but they go onopposite sides of the front wall 9.

The flaps I5, previously referred to, extend forwardly and are connectedonto the flap 9, the interconnecting portions or web consisting oftriangular portions 29, and substantiaily triangular portions 30.Between each of the portions 29 and 30 a score 3| and a'slit 3 2 areformed. See Fig. 3.

The webs are folded together by pushing the intermediate creases orscoresv outwardly and this causes the flap 9 to raise to a position asshown in Fig. 4. Prior to this movement the box is as shown'in Fig.2.That is. the sides I! have been folded upwardly so as to lie at rightangles to the bottom It and the flap 9. Also, the back II has beenfolded upwardly at right angles to the bottom ID, the flaps I! havingbeen folded inwardly so that their terminals enter the slits l5, and thetop 12 is positioned above the bottom member I0. See Figs. 2 and 5.

The next step is the folding rearwardly of the doubled flaps, 29, 30,from their position as shown in Fig. 4 so as to lie alongside of thesides l5. See Figs. 5, 6, and 7.

When in this position the upper side flaps 2|, these being foldeddownwardly to assume aposition outside of the flaps l5, cause the tabs21 to enter between the web portions 29 and 30. The start of this entryis indicated in dotted lines. in Fig. 5 of the drawings. The front flap.ll may enter inside of the lower front flap 8. The looking means 21,carrying the cars 50, see Fig. 8, islocked onto the front flap 9, theears entering the slits 5| formed in the front 9. See Figs. 4

and 8.

As is shown in Fig, 8, the inner ends of these slits 5| are curved at52, this providing against having any abrupt obstruction in the path ofthe plate or the like which carries the wedding cake or the like." Thatis, even though the portion of the flap 9 encircled by either of theslits 5i may be raised, nevertheless it will be gradually forceddownwardly to an unobstructive position by a gradual camming actionbetween the encircled portion and the bottom of the cake carrying means.

Fig. 9 indicates a modified form'in which the,

'upper side flap 54, corresponding to the side flap 2|, has a notch 55adjacent its tab 56, this notch serving to receive the lower edge of thelocking pocket. Thus additional means are provided; for preventingshifting of the top member.

As will be appreciated, the box may be folded to its partly closedposition as indicated in Fig. 2, and the cake 51, or pie, or pastry, asthe case may be, carried by the support 58, may be slid to a positioninside of the carton without the slightest multilation thereof, and,perhaps of more importance, the cake may be expediently removed by thehousewife or other purchaser. without reaching downwardly around thesame. In other words, the box may be unlocked by means of the 'lockingtab 21 whereupon the front wall 9 is pulled downwardly to assume a flatposition as shown in Fig. 2 of the drawings and the cake is easily slidout. V

From the foregoing description, it is thought to be obvious that a paper-box constructed in accordance with my invention is of an extremelysimple and comparatively inexpensive nature and is particularly welladapted for use by reason of the convenienceand facility with which itscontents may be entered and removed, and it will also be obvious that myinvention 'is susceptible.

of some change andmodiflcation without material departure 'from' theprinciples and spirit thereof and for this reason I do not wish to beunderstood as limiting myself. to the precise arrangement and formationof the several. parts herein shown in carrying 'out my invention inpractice.

1. A carton comprising bottom, back, top and flap sections hingedlyconnected together in series, sides extending upwardly from the bottom,additional sides extending downwardly from the top, portions joinedto-and between each of the first mentioned sides andthe adjacent end ofthe flap section, said portions being folded along the first mentionedsides to form pockets and means, connected to the additional sides,receivable into the respective pockets.

2. A carton comprising a bottom and a top, side's extending upfromthebottom to the full height of the carton, additional sidesextending downwardly alongside of the first mentioned sides for arelative short distance with respect to the height of the carton, a webbetween each of the sides of the bottom and the ends of the adjacentflap section, said web being foldable rearwardly to form a pocket andmeans on the additional sides for entering the said pockets.

3. A carton as set forth in claim 2 in which the said pockets and themeans entering the same are provided with means for causing the top tomove forwardly to its properly closed position, if necessary, as it ismoved downwardly.

4. In combination, a carton having a bottom and four sides, one of thesides being hinged onto the bottom, webs between the hinged side and theends of the adjacent sides, each of said webs having a score extendingfrom the adjacent corner whereby the web may be folded alongside of theouter face of the adjacent side, a lid adapted to be swung downwardly toa position juxtaposing the'top edges of the several sides, and means onthe lid adapted to enter between the inner faces of the webs.

5. A combination of elements as set forth in claim 4 in which a portionof the web immediately adjacent the hinged side is cut awayand theremainder of the web is rounded.

6. In a corner construction for a box, a bottom having intersectingsides, a web connecting the same, a top having a depending flap, the webbeing of suflicient length to permit one of the sides to assume aposition in the plane 'of the bottom, a score in the .web to permit itslateral movement and also to be swung to a position alongside of theother of said sides,the top flap .having a projection receivable intothe space between the inner faces of the web.

7. A corner construction as set forth in claim 6 in which the receivableprojection is cut at an angle for the purpose described.

8. A' corner construction as set forth in claim 6 in which the flapcarrying the projectionhas a notch adjacent thereto to receive the edgeof the pocket for the purpose described.

struction comprising a top member and depending means for engaging thewebs at points spaced from theiunctures of the front wall and the sidewalls to prevent downward movement of the front wall.
